Terminal services connect from Win2k client using port 90 or 21
I have a client running Win2k machines on a large company network that only allows connecting via the Internet through ports 80 and 21 and their local IT department cannot change this restriction. I want them to be able to connect to my SBS 2003, which is on a separate network, via Terminal Services.
They can get to the Remote Web Wokplace on my server and see the server name but when they click the Connect button they get an error message. Their IT department says it is because my terminal server uses port 3389. I have tested connecting to my SBS server using a Win2k PC not on their network and it works fine and they have done the same and say it works fine.
